I was looking for wrist rest designs, but could not find anything I liked.
This is the second major iteration of my 3 part design. Adjusted the drop off angle after long term use. Now it is more comfortable. I recommend printing the pads from TPU with 5% Gyroid infill and 2 bottom layers, but they work completly fine printed in PLA as well (not as comfy though :D). Blank middle part and step file included, for easier customization.
Remix it to make it unique and just yours, and share a make if you liked it!
Parts should be printed with the top side on the build plate (for better quality for the visible side) and can be printed without support.
Recommendations are always welcome. If you decide to print it, please let me know how it worked out for you. Also open to adjust it for other keyboard sizes, if there is a need for it.
Update: Added middle part with tighter tolerance for those who have better calibrated printers.
Update 2: Added middle part with honeycomb pattern, plus few new photos (Esun Temperature color change TPU). Tested with 2 bottom layers as advised by @chroma_1060047, added to recommended print settings.
